Why now

Most teams still justwrapAI.

You should be compounding it — shipping systems that get cheaper, smarter and more valuable every quarter.

Services

Three ways to work with me — each engineered for compounding ROI.

Every engagement starts with a free 30-minute consult so pricing fits your problem, not a template. Walk out with a firm, outcome-priced quote inside 48 hours.

01 / 2 weeks · outcome-priced

AI Strategy Sprint

Two weeks of interviews, data review and architecture calls. You leave with a ranked opportunity map, a ROI model per bet, and a 90-day plan your team can run the Monday after.

  • Full stack audit and data readiness review
  • Opportunity map ranked by ROI and technical risk
  • 90-day build plan with owners and go/no-go gates
  • Executive-ready deck and live briefing

Agentic Systems Build

I ship a production agent or AI feature end-to-end — evals, guardrails, observability and the ops handoff. Your team owns the repo, the runbooks and the roadmap when I leave.

  • Production RAG, tools, memory and eval harness
  • Cost and latency budgets hit before launch
  • CI/CD, observability and on-call runbooks
  • Team handover with internal docs and walkthroughs

03 / monthly retainer

Fractional AI Lead

Embedded with your team as head of AI. I own roadmap, hiring and vendor calls so your execs stop guessing. 30-day cancel, no lock-in.

  • Roadmap ownership and weekly execution reviews
  • Vendor and model selection (OpenAI, Anthropic, open weights)
  • Hiring bar-raising and technical interviews
  • Quarterly board readouts with metrics that matter
Retainer sized to your team

Process

Five steps, zero theatre.

How engagements actually run, from a discovery call to a system your team owns and extends.

Discover

Two weeks of interviews, data pulls and workflow mapping. We leave with a ranked opportunity map, not a wish list.

Design

I spec the system the way a senior engineer would: contracts, evals, guardrails, cost and latency budgets, runbooks.

Build

Small weekly releases behind flags. Every change ships with tests, traces and an eval gate. No demo-ware.

Deploy

We cut over behind a shadow window and measure the real thing — $ saved, cycle time down, CSAT up.

Compound

We layer the next bet on top. The goal is a system that gets cheaper and smarter per quarter, not a one-off win.

Testimonials

The short version from the operators I worked with.

Himanshu replaced eight months of prototypes with one system that paid for itself in the first quarter. He ships like a staff engineer and presents like a partner.

The consult gave us a scalpel. We killed two pet projects, doubled the headcount on the one that mattered, and shipped it 40 days later.

He held our team to a bar we could not hold ourselves to. The evals he left behind are still our release gate.

FAQ

The questions every serious client asks before the first call.

I don't publish fixed fees because no two engagements are priced the same. Scope, timeline, data maturity and on-call risk all move the number. Every engagement starts with a free 30-minute consult; you get a firm, outcome-priced quote inside 48 hours, with no obligation to continue.
Strategy engagements run two weeks, kickoff on a Monday, readout two Fridays later. Builds ship an internal alpha in 3–4 weeks and hit production in 6–12. Fractional engagements are three months minimum because roadmap work needs time to compound.
You do. I ship into your repositories from day one, use your cloud accounts, and leave behind architecture docs and runbooks. I keep a generalised, redacted playbook of patterns — never your code, models or data.
We default to your VPC, your keys and your retention policy. I have shipped under SOC 2, GDPR and HIPAA-adjacent constraints and can work with your DPO to build DPIAs. Nothing leaves your tenant without a written sign-off.
Week 1 I sit in your standups, read the last quarter of incident reports, and talk to three customers. By Friday you have a one-page diagnosis and the bets I will take. No 60-page deck, no theatre.
Strategy engagements have a milestone check at the halfway mark; if the direction isn't landing, you can walk away and only pay for work delivered. Builds are milestone-priced so you never pre-pay a milestone you haven't accepted. Fractional retainers are 30-day cancel.
I run at most two fractional engagements and one active build at a time. For strategy work, I commit to no competing clients during the engagement window. Broader exclusivity is negotiable and priced separately.
London, UK. Most clients are in UK, EU and US Eastern time zones. I travel for kickoffs and quarterly readouts. Remote-first on Linear, Slack, Loom and GitHub.
08 / Let's talk

Let's compound your next quarter.

Thirty minutes is enough to know if there's a fit. Walk in with the ambiguity, walk out with the first three bets.
